The models are made of solid aluminum, are precision die-cast, and
are painted.

Each model is 3.20 cm (1.26 inches) in diameter.
Each set comes in a clear, reclosable, plastic clamshell container.

Model sets also make great awards for mathematical achievements.
They have been official prizes

The polyhedra models made by Pedagoguery Software are just the thing to stimulate thought and exploration among students of any age. What properties have shapes, as different as these, in common? By playing with them, running your finger over their boundaries and turning them around in the light, insight is sparked.—Robert L. Kaplan

I have your models on my desk and many visitors are amazed by their beauty and utility.—Professor István Hargittai

Got the polyhedra—wow! They are wonderful. I may be purchasing some more sets. Much appreciated!—Professor Joseph O’Rourke

The models are lovely—my colleagues are delighted with the set I have given to the Department of Mathematics.—Professor Victor E. Hill IV

It is a special pleasure to have these handsome specimens on my desk.—Dr. Peter Pesic

Your models arrived yesterday and they are beautiful. It is startling how crisp the corners are, particularly on the tetrahedron. They are a terrific addition to my exhibit.—Professor Michael Henle

The solids arrived yesterday, and they are BEAUTIFUL! I also liked the nice packaging.—Professor Eli Maor

These are beautiful objects to behold. I was reminded of the wisdom of Ralph Waldo Emerson when he said: ‘We ascribe beauty to that which is simple; which has no superfluous parts; which exactly answers its end. which stands related to all things; which is the mean of many extremes.’; These Polyhedra are beautiful because they are simple; they have no superfluous parts; they exactly answer their ends; they stand related to all things; they represent the mean of many extremes.—Professor S. J. Abas

These models are not only a delight for all geometers but also for all aesthetes who are lucky enough to see them and any person of sensibility who is lucky enough to touch them.—Professor Emeritus Peter Hilton and Professor Jean Pedersen

Your polyhedral creations arrived while I was in California, and I am delighted to have them. For my book, ‘Math and the Mona Lisa,’ I had created images of the five basic polyhedral solids—in addition to a number of truncated, tessellated and stellated variations—using MATHEMATICA. I am delighted to have in my possession now the tangible solid forms in hand. They are indeed beautifully engineered and a wonder to hold.—Professor Bulent Atalay
